Alarm: Host average disk queue length
Time: 5/30/2019 1:43:36 AM
Details: “Disk/Host: Avg Disk Queue Length” (3.0 Number) is above a defined threshold (2.0 Number) for ‘C:’;

KB article
Summary: Average disk queue length on the host may report on too many I/O requests. This means that not all requests are queued. Some requests are completed and are on their way back to where the performance data is being collected
Cause: As a general rule for hard disks, an Avg Disk Queue Length greater than 2 (per hard disk) for extended periods of time is considered undesirable. If you have a RAID system with 8 disks, you do not want an Avg Disk Queue Length greater than 16. A queue length of 32 might indicate this disk is saturated and is the bottleneck in the system
Resolution: Faster hard disks with quicker access times (and therefore I/O) will allow greater flexibility with Avg Disk Queue Length numbers. Also if you have any concurrently running resource intensive tasks (backup jobs, antivirus checks etc.), consider using different time schedule in order to offload you host disks
